Our company introduces advanced international technologies to design, develop, and manufacture the no-partial discharge (PD) power frequency test transformer. It is widely used by manufacturers of electrical appliances, cables, motors, transformers, instrument transformers, insulation materials, and related high-voltage components, as well as high-voltage test laboratories in power generation, scientific research, and universities. It can perform partial discharge and power frequency withstand voltage tests on these products.

Main Features

1. Filled with high-insulation SF6 gas as the insulating medium;

2. Compact size, light weight, high-grade craftsmanship, beautiful appearance, and easy transportation;

3. Due to the arc-extinguishing properties of SF6 gas and its unique process structure, the partial discharge (PD) is minimal, reaching ≤5 PC at rated voltage.

4. The test process is simple and intuitive, making operation easy and convenient;

5. It effectively eliminates noise interference from the power supply;

6. Utilizes automatic control technology, offering a high degree of automation and strong anti-interference capabilities;

7. Utilizes fast-acting electronic protection devices for high reliability.
